The dcmdedit utility can split resulting single dives into multiple dives or join multiple dives into a single dive. Its arguments are as follows:
Join a sequence of dives within a divelog into a single dive.
Split a single dive into a sequence of dives by its surface intervals.
Emit warnings during parse. Specify twice for further debugging information.
If there are multiple dive computers specified, or multiple divers, the first is selected to represent all output dives.
Splitting (-s) is useful for establishing “canonical free dive mode”, wherein each dive in a sequence has its own dive profile and surface time is omitted. Many dive computers automatically produce canonical free diving mode, for example, the Suunto D6i. Others, like the HW OSTC 2C, do not, and instead put all dives into one, including surface time. The new split dives are given a fingerprint formatted as fingerprint-num, where “fingerprint” is from the dive being split.
Joining (-j) is useful when exporting data into Subsurface, which expects a single dive profile. Here, a set of dives are merged into a single one. The new merged dive is given a fingerprint formatted as fingerprint-join, where “fingerprint” is from the first dive entry.
If dives already are split, -s does nothing; same goes with -j and dives already being joined. For both modes, dives not using the same dive computer as the first (by date) are omitted. The diver identity is ignored.
If invoked using neither -j nor -s, all dives are merged into a single divelog. All dives must have the same dive computer as the first (by date), else they are omitted, and duplicate fingerprints are also omitted.
dcmdedit produces output on standard output as documented in dcmd(1).

The dcmdedit utility exits 0 on success, and >0 if an error occurs.
